Ringing in Ears from Fluid Behind the Eardrum?

Hello,
A couple of days ago my ears got really stuffed up and i started to hear ringing in my ears, so i went to the doctor, and he gave me some nasal spray and told me i had clogged eustachian tubes. I took the nasal spray for a couple of days, and nothing changed. I went back to the doctors and then they told me i had fluid behind my eardrums, and prescribed me Zertek and antibiotics. They said it would go away on its own, but i'm getting really worried. Every night i have trouble sleeping, and the sound of the ringing varies throughout the day.

I read some of the stories on this website, and i'm starting to get scared. Is this ringing going to go away once the fluid clears up? I'm 14 and i also have a cold.

 

Have you sorted this out now? I have the same problem
